[Overview] OutOfMemoryError

[AlvaroBrey]

This issue is here to concentrate in one place all out of memory error traces.

So far, the most usual reasons for OOM to happen:

Uploading lots of files

This seems to be more frequent since new uploader was introduced

• https://github.com/nextcloud/android/issues/10653 and duplicates -> crashes while uploading
• https://github.com/nextcloud/android/issues/11066 and duplicates -> crashes when restarting failed uploads

Streaming large videos

• https://github.com/nextcloud/android/issues/9428 and duplicates

Browsing media

• https://github.com/nextcloud/android/issues/11132

Other random issues

• https://github.com/nextcloud/android/issues/11060 <- idle, crashes in ThreadLocalWorkSource
• https://github.com/nextcloud/android/issues/9639 <- when syncing e2e folder
• https://github.com/nextcloud/android/issues/10633 <- too many clonflicts

Is there a solution to this?
